AC & Heating Tips
In the summer, help reduce electricity usage and costs.*
Set your thermostat four degrees higher when you're away for more than four hours.
Set your AC fan to the “auto” position rather than the "on" position.
Using the "on" fan setting can increase your costs because the AC will be working to run the fan even when the room has reached your desired temperature.
If you have an electric heater, lower your thermostat to reduce your electricity usage.
For every degree above 68°F, expect an approximate 3% to 5% increase in your heating costs.
Reduce the thermostat on your electric water heater to 120°F.
You could save 3% to 5% in energy costs per year.
In the winter, rotate your ceiling fans clockwise.
Running your fans at a low speed forces cooler air upward.
Additional AC and Heating Tips
Tune up your heating, ventilating and air conditioning (HVAC) system with an annual maintenance contract.
Even a new ENERGY STAR® certified HVAC system, like a new car, will decline in performance without regular tune-ups. A contract ensures that your HVAC contractor will provide "pre-season" tune-ups before each cooling and heating season. You save energy and money, and your system may last years longer with minimal costs for yearly maintenance fees.
Regularly change (or clean if reusable) HVAC filters every month during peak cooling or heating seasons.
New filters usually only cost a few dollars. Dirty filters cost more to use, overwork the equipment and result in lower indoor air quality.
Control direct sun through windows, depending on the season and local climate.
During hot seasons, block direct heat from sunshine on the east side and especially the west side of the facility. Depending on your facility, options such as solar screens, solar films, awnings and vegetation can help keep facilities cooler. Over time, trees can attractively shade the facility and help clean the air. Interior curtains or drapes can help, but it's best to prevent the summer heat from getting past the glass and inside. During cold seasons, with the sun low in the south, unobstructed southern windows can contribute additional heat during the day.
Install a smart thermostat.
Instead of relying on manual adjustments, install a climate control system that adjusts according to the patterns of your business. New systems will automatically adjust the temperature a few degrees in either direction as they learn your schedule, plus they are usually accessible through a mobile device so that you can program or adjust them from anywhere. Options such as the Reliant Business Smart Controls plan will give you control of multiple locations at once and alert you about system performance issues.
Plug leaks with weather stripping and caulking.
Caulking and weather stripping let you manage your ventilation, which is the deliberate, controlled exchange of stuffy inside air for fresher outdoor air. To learn more about indoor air quality in your facility, visit the Environmental Protection Agency's website on indoor air quality.
Moving air can make a somewhat higher temperature and/or humidity feel comfortable.
Fans can help delay or reduce the need for air conditioning. And a temperature setting of only three to five degrees higher can feel as comfortable as your normal setting if you use fans. Each degree of higher temperature can save about 3% on cooling costs. When the temperature outside is more comfortable than inside, a box fan in the window or large whole-facility fan in the attic can push air out and pull in comfortable air from outside.
